ROCKING AND REVERSING GRA'TE.

SPECIFICATION forming part of Letters Patent No. 688,105, dated December3, 1901.

Application filed July 8, 1901. Serial No. 67,520. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JAMES N. LONG, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainhereinafterset forth, reference being had to v the accompanying drawings, inwhich-- Figure 1 is a transverse section of a grate constructed inaccordance with my invention; and Fig. 2 is a plan View of the same,partly in section.

1 represents the outer frame of the grate, which in the present instanceis rectangular; but it may be of circularor other desired shape,depending upon the shape of the fire-pot in connection with which it isto be used. Within this outer frame are hung the grate-bars 2, of whichas many may be used as desired, five being shown in the drawings, eachof said grate-bars having at the ends trunnions 3, adapted to bearingsin the frame 1, so that each bar is free to rock within the frame. Theframe 1 also has trunnions 4-, by which it may be hung in the fixedframe of the stove or heater, so as to be tilted for dumping thecontents of the fire=pot into the ash-pit, the front trunnion 4: beingtubular for the passage of the front trunnion 3 of the central grate-bar2, whereby power may be applied to said grate-bar to rock the same.

The central grate-bar and the two bars flanking the same have upon eachside a toothed segment 5, and the outer bars of the series have suchsegments on their inner sides, the toothed segments of adjoining barsmeshing with each other, so that power ap plied to the central bar torock the same will be transmitted therefrom to the other bars of theseries and will cause a like rocking movement of each of said bars. Inthe present instance the bars have these toothed segments at thelongitudinal center of each bar; but the segments may bear any otherdesired relation to the bars, or each bar may have two or more of thesegments disposed throughout its length, if the use of more than onesegment on the side of each baris considered neeessary for the purpose.When this method of gearing together the bars of the grate is adopted,no burning out of the connections or other bad result will follow if indump ing the grate the same is accidentally re versed and left in thatposition, since the building of the fire upon the gratein the reversedposition will have no ill effect either upon the bars or theirconnections.

Having thus described my invention, I claim and desire to secure byLetters Patent-- A grate havinga frame with trunnions centrally disposedthereon whereby it is pivoted so as to be reversible, one of saidtrunnions being tubular, and a series of gratebars pivoted within saidframe so as to be capable of rocking therein, said bars being gearedtogether byintermeshing toothed segments formed upon the sides of thebars, and the pivot-trunnion of the center bar of the series passingthrough the tubular pivottrunnion of the outer frame, substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES N. LONG.
